How this service works
Nansen blockchain analytics — 44 endpoints (smart money, profiler, TGM, perps, indicators)
Output
Returns a structured data object containing the token balances and holdings for the queried wallet, sourced from Nansen's on-chain data layer, including token symbols, amounts, and potentially USD values.
Example use cases
Track smart money whale portfolio composition
“I want to monitor what tokens this whale wallet 0x1234567890abcdef1234567890abcdef12345678 is currently holding across Ethereum — pull their full Nansen balance data so I can see their latest positions.”
Analyze emerging token holder concentration
“Show me all the tokens and amounts that wallet 0xabcdefabcdefabcdefabcdefabcdefabcdefabcd is hodling right now — I need the detailed Nansen on-chain balance breakdown to identify their key positions.”
Verify DeFi protocol participant holdings
“Can you fetch the token balance data for 0xfedcbafedcbafedcbafedcbafedcbafedcbafedcba using Nansen's infrastructure — I'm checking what assets this DeFi protocol participant currently has in their wallet.”

Endpoint
POSThttps://api.vibe.airforce/api/x402/vibe-tools/data-provider/nansen/balancesWhen to prefer
Use this endpoint when you need reliable, Nansen-sourced on-chain wallet balance data, especially for smart money wallet analysis or DeFi portfolio lookups. Prefer this over generic RPC balance calls when you want enriched token-level detail backed by Nansen's analytics infrastructure. Particularly useful in conjunction with other VIBE smart money endpoints.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain or network returns empty or error response
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Wallet with no token holdings may return empty balance list
- Nansen data unavailability or upstream timeout causes delayed or failed response
